@Johntheo5 I'm not sure, it's quite boxed in which doesn't make it easy to figure out what goes where. I've added some pictures, hopefully makes sense I'll also add that I checked the water temp coming out this morning and it's hot water.

Hi, I'm new to unvented hot water systems. Recently I've noticed water leaking through the tundish, it's almost a steady flow. If I turn on the hot water tap for a few moments it stops running I'm guessingbdue to the drop in pressure. I wouldn't say the hot water is excessively hot. The cold...

I have a saunier duval isofast condens f35e boiler. Over the winter it has continually dropped pressure from 1bar to 0.7 in about 5 days. There is water coming out of the pressure relief outlet when the central heating is on. I tested to see if there was air in the 10ltr expansion vessel...

It's a reasonable problem in that I have to top the boiler up pretty frequently. Although it can vary from every other day to once a month. Thanks will get a plumber out.

Thanks for the prompt replies. Yes it does leak while topping up, normally a dribble when I close the top up valve. It does leak during operation though as I have to keep a small cup underneath. Would this cause the pressure to drop? Any estimates on cost to replace, thanks

HI, I'm wondering if any kind persons on this site will help me identify the part which I believe is causing the loss of pressure from the boiler. There is a threaded pipe under the boiler which leaks during operation. With it being a closed system I can only imagine this is causing the drop in...

Hi, I had a new indian sandtone patio put down about 3-4 weeks ago. It was set on a mortar bed but after a short time it looks like the pointing has failed completely. One of the slabs on the end can be easily lifted out of place. There is movement in a few slabs. I have attached...

Sorry, I've investigated a little further and the water is coming from the nut joining the copper pipe to the top left of the boiler. There are 2 pipes going in and it visibly leaks when the central heating is on. I've tried to tighten it by hand but can't turn it. It is in a very difficult...

Just to ask the question in another way, does anyone think that the leak I spot from the boiler when the central heating comes on result in the pressure loss? Also the upstairs rads are filling with air, I take it thats because the water has to be replaced by something? The water is running...

I wouldn't have the first clue how to fix it though. Would that also allow air into the system as I have noticed a small amount of air coming out of an upstairs radiator? I take it I am right in thinking that would be a sufficient leak and I haven't got a problem in the pipework? Cheers

Hi all, I have been dropping pressure for the last 2 months approx 0.1 bar / day. Recently this has increased to as much as 0.3bar. I took the casing off the boiler and saw water marks underneath the chamber. When the central heating comes on there is a steady drip from the fan. Could this...
